WILLIAM A. MILES, OF COPAKE IRON WORKS, NEW YORK.

CONDENSER FOR PUMPING-ENGINES.

To all whom it may concern:

Be it known that I, WILLIAM A. Mines, of Oopake Iron Works, in the county of Golumbia and State of New York, have invented an Improvement in Condensers for PumpingEcgines, of which the following is a specification. This improvement relates to that class of pumping-engines in which the exhaust-steam is discharged into the suctionwater-way and is condensed by the water that is pumped.

In apparatus of this kind ditliculty has heretofore existed in obtaining a free discharge of air and of the water of condensation.

My present invention is for simplifying the construction of the condensing apparatus, and for removing the air and steam in a more reliable manner than heretofore.

' In the drawings, Figure 1 represents the improvement by a vertical section. Fig. 2 is an inverted plan at the lineman, and Fig. 3 is a section of a modification of my condensing apparatus.

1 make use of a suction-pipe, A, extending from the water to the pump and forming the suction water-way. Around this pipe A'there is a ste'amjacked'B, into which the exhauststeam pipe 0 opens. At the bottom of the steam-jacket B there are one or more openings into the suction water-way, so thatany water of condensation will run or be drawn out of the jacket B into the said water-way, and should there be air with the exhaust-steam,it will descend as it is displaced by the steam, and it will be drawn off with the water in the suction-pipe A to the pump. I

1 make use of any suitable opening between the endof the steam-jacket and the waterway. I have shown said opening as a range of holes,,s, and a valve, '5, placed upon the under side of the valve-seat, said valve-seat forming the lower end of the steam-jacket, and having openings through said valve-seat, as seen in Fig. 2.

The valve itself may be a disk of sheet metal clamped at its edges between the flanges of the-jacket and the enlarged upper end of the water-pipe. This disk of metal has a central opening coinciding with the central water-way,- .so as not to obstruct the same. This valve SPECIFICATION formingpart of Letters Patent No. 272,458, dated February 20, 1883.

I Application filed December 26, 1882 (No model.) I

deflects the steam into the water as the latter is drawn along in the suction-pipe A, and causes it to pass in a thin stratum and condense rapidly.

I remark that usually theextent of surface in the condensing-jacket will be sufficieut to cause the steam to condense, so that only water and air or gases will be drawn out through the valve.

Ifdesired, the water may surround the con I dancing-vessel, as indicated" by dottedlines; or. the condensing-vessel may be simply acylinder inside the water-way, and the valve at the bottom be secured in the middle instead of at the edges, as seen in Fig. 3, the operation of the parts being the same as before described. y

- In'place of having a valve at the opening from the condensing-vessel into the suction water-way to check the passage of water into the condensing-vessel, a check-valve might be applied in the steam-pipeybut it is preferable to use the check-valve, as shown.

I claim as my invention 1. In a condenser for pumping-engines, the combination, with the suction water-way, ot'a condensing-vessel and an opening from the bottom of-the condensing-vessel into the water-way, and avalve at said opening, substantially as set forth.

2. The combination, with the suction waterway A, of ajaoket surrounding the water-way, having an opening at or near the bottom for the water of condensation and any atmosphere to be drawn into the suction water-way, substantially as set forth.

3. The combination, with the suction waterway, of a condensing-vessel, an opening in the same at'or near the bottom for the water of condensation and air to be drawn into the suction water-way,-and a check-valve, substantially as set forth.

Signed by me this 21st day of December, A. D. 1882.

WILLIAM A. MIL-ES.
